Refund request

I have a mobile contract with Telkom, which I have requested them to close or cancel and I was advised the contract will be canceled on the 20th of November so I received my monthly statement and the is credit on my account for about R595.00 so I logged a query for a refund and I was advised it should be resolved within 72 hours now I have called Telkom twice to follow up on also sent out a message on their communication platform because there has not been any feedback whatsoever from their end when I track the issue myself it's forever been stuck on step one no progress or anything along those lines *** can just for once Telkom do what is expected of them without one having to fight because now I'm being told the accounts department is closed because it's weekend when I logged the request way before the weekend.
